I tried about 20 different notepad replacements before I found true happiness with Win32pad, thanks for the great (and free! program.

Only problem I have found (and it is a tad annoying) is that I keep my taskbar at the top of the screen, and Win32pad suffers from the "vertical creap bug" that some programs seem to have. Basically every time its closed and reopened, it locates itself a few pixels higher and higher, until it is under the taskbar. I have seen this discussed (and fixed) among programmer, perhaps search google?
